Counterfeit 2009 Kew Gardens 50p coins are known to exist. The style is similar to the fake Magna Carta £2 coin and others that can regularly be purchased direct from a Chinese auction website. I always find that the eye (of the Queen) is the most obvious giveaway, as for some reason forgers often have difficulty getting the eye detail right. The forgery on this page at 7.2 grammes is also 10% lighter than a real one which should be 8 grammes. It’s diameter is also a tiny amount less than the 27.3mm that it should be.

The obverse is easiest to identify as a fake. Slight differences also exist on the reverse, relating to the tower and the word ‘Kew’.
